DESCRIPTION
The TSM104 is a monolithic IC that includes four
op-amps and an adjustable shunt voltage refer-
ence. This device is offering space and cost sav-
ing in many applications like power supply man-
agement or data acquisition systems.

The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the
common-mode voltage range is V
